Lucid carpet

ID changed to Chrysolarentia lucidulata - 'Lucid carpet'

Thanks for that ID martin. That's amazing. I'll have a look at EOL now.

The BOLD link pics are pinned specimens and clearly from somebody's old collection. Sometimes a photograph of a fresh specimen provides useful information about a species that a pinned specimen no longer provides.

You could donate a copy of your excellent photo - I have sent about 50 photos to EOL (via flickr) to add to their reference collection

That's an excellent match on the waves and carpets.
Pity about the yellow. Could it be just lost scales? (the specimens in the BOLD link look quite tired)

Argybee. I have a little booklet from Peter Marriot "moths of Victoria" Vol III Waves and Carpets. Geometroidea - Larentiinae. There are maybe 200 photos. The link seems to lack the yellow skirt, but my reference photo is a perfect match.

...and those who studied it long ago say they can't believe how much it has changed... what fun!! :)

@Argybee,
Argybee one just can't win! I studied biology, but it is so long ago, I can't remember!

nice one!
